Worst Case Consequence is a concept in risk management that is the most conservative estimate of consequences of the most severe accident identified. The Worst Case Consequence is usually used to define the low probability-high consequence outcomes with the maximum negative consequences (fatality, environmental pollution, material loss). (e.g., The largest quantity of a hazardous substance from a single vessel or process line failure that is released to the most vulnerable area in such a way (all at once or continuous) as to have the maximum effect on the public or employees in that area).
